Application & Features

For use as overhead power source on streetcars, trolleys, electric trolley buses, light rail and heavy mass transit systems. Also used on electrically powered mine train, and industrial cranes. High-tensile strength properties allow for reduced clearance maintenance in tunnel applications. Southwire bronze contact/trolley wire is ideal for transportation systems with increased line speeds just over 200 mph (322 km/h).

• High Tensile Strength and Breaking Load
• Highest Half-Hard Value of any Materials in Present Day Use.
• Durable and Reliable Support.
• Allows for Increase in Max Line Speeds
• Mechanically Rugged
• RoHS/Proposition 65 Compliant
• Ships on N-42 wooden reels (S-77 steel reels available per SW reel policy)
• Available with top lobe identification marking per IEEE 1896-2016
• Southwire SPEED Qualified for low volume requests
• Buy America Compliant

Construction

This product combines excellent wear characteristics, and high-tensile strength properties. Contact/ Trolley wire is available in a choice of two alloys to provide the best match of electrical and mechanical wear properties for each application - 55 percent and 80 percent conductivity IACS (CA165 and A162), and is offered in both ASTM and EN/IEC configurations: round (upon request), grooved, figure 8, or figure 9.
